Manifold & Cylinder Head

Before Rework

Note:

Check whether the cylinder height permits reworking.

Check to see if nozzle tip protrusion will retain within specified limits after rework.

Nozzle protrusion of 2.3/1.8 mm/0.90”/0.70” is to be ensured.

To remove valves compress valve springs with compressor tool and take out spring retainer
locks.

Clean the cylinder head thoroughly.

Remove carbon deposits from the bottom of the cylinder head and out of exhaust valve ports.

Flush out the water jacket to remove scale and dirt.

Assembly: -

Insert 2 no, M8 studs. Use stud tightening tool to tighten the studs.

Similarly tighten 3 nos, M10 injector holding studs. Place Engine Lifting bracket and tighten M10
Bolt.
